Wireless NoC is becoming popular to be a promising future on-chip interconnection network as a result of high bandwidth, low latency and flexible topology configurations provided by this emerging technology. Nonetheless, congestion occurrence in wireless routers negatively affects the usability of high speed wireless links and considerably increases the network latency, therefore, in this paper, a congestion-aware platform (CAP-W) is introduced for wireless NoCs in order to reduce both internal and external congestions. The whole platform of CAP-W consists of an adaptive routing algorithm that balances utilization of wired and wireless networks, a dynamic task mapping approach that tries to minimize congestion probability, and a task migration strategy that considers dynamic variation of application behaviors. Simulation results show significant gain in congestion control over PEs of wireless NoC, compared to state-of-the-art works.
